In Bangladesh, approximately 31% of urban residents are living without safely managed sanitation, the majority of whom are slum residents. To improve the situation, Dhaka Water Supply and Sewerage Authority (DWASA) is implementing the Dhaka Sanitation Improvement Project (DSIP), mostly funded by the World Bank. This study assessed the challenges and opportunities of bringing low-income communities (LICs) under a sewerage connection within the proposed sewerage network plan by 2025. We conducted nine key-informant interviews from DWASA and City Corporation, and 23 focus-group discussions with landlords, tenants, and Community Based Organisations (CBOs) from 16 LICs near the proposed catchment area. To achieve connections, LICs would require improved toilet infrastructures and have to be connected to main roads. Construction of large communal septic tanks is also required where individual toilet connections are difficult. To encourage connection in LICs, income-based or area-based subsidies were recommended. For financing maintenance, respondents suggested monthly fee collection for management of the infrastructure by dividing bills equally among sharing households, or by users per household. Participants also suggested the government's cooperation with development-partners/NGOs to ensure sewerage connection construction, operation, and maintenance and prerequisite policy changes such as assuring land tenure.
在孟加拉国,约有 31%的城市居民无法安全地使用环境卫生设施,其中大多数是贫民窟居民。为了改善这种情况,达卡供水和污水处理局(DWASA)正在实施达卡环境卫生改善项目(DSIP),该项目主要由世界银行提供资金。本研究评估了在 2025 年前将低收入社区(LIC)纳入拟议污水管网计划的挑战和机遇。我们对 DWASA 和市公司进行了 9 次重点访谈,并在拟议集水区附近的 16 个 LIC 与房东、租户和社区组织(CBO)进行了 23 次焦点小组讨论。为了实现连接,LIC 需要改善厕所基础设施,并连接到主要道路。在难以实现个人厕所连接的地方,还需要建造大型公共化粪池。为了鼓励 LIC 进行连接,建议根据收入或地区提供补贴。为了筹集维护资金,受访者建议按户均摊或按户收费的方式,由共用家庭平等分担,由用户支付基础设施管理费用。参与者还建议政府与发展伙伴/非政府组织合作,以确保污水连接的建设、运营和维护,并进行必要的政策改革,例如确保土地保有权。
